Nests in Trees, Bushes, or Vines 



663a. Sycamore Warbler: D. d. albilora Ridgw. 



Closely resembling the preceding, but rather smaller, and 

 without yellow in front of the eye. 



Breeding Range — "The Mississippi Valley north to Kansas, south- 

 ern Indiana, and southern Illinois ; east to western South 

 Carolina" (Chapman). Davie gives the range as, "North 

 to Lake Erie and southern Michigan, and east to western 

 North Carolina." 



The nest is usually placed in sycamore trees. "It is com- 

 posed of fine shreds of vegetable material intermingled with 

 short, slender twigs as the base." 



The eggs are identical in markings with those of the yellow- 

 throated warbler, but are slightly smaller in size. 



667. Black-throated Green Warbler: Dendroica virens 



(Gmel.) 



Adult 3 — Upper parts olive green ; two white wing bars, bright 

 yellow cheeks, and hne over eye ; under parts, throat, 

 breast, and streaks on sides of flank b'ack ; belly white, 

 more or less tinged with yellow. 



Adult $ — Very similar, the throat having yellow mixed with 

 black. Length — 5.10. 



Breeding Range — The higher parts of the AUeghanies to South 

 Carolina, and northward from Connecticut and northern 

 Illinois. 



The nest is a beautiful compact structure of small twigs 

 (usually of hemlock or spruce), lichen, moss, grass, wool, and 

 bark, lined with plant down, hair, grass, and feathers. It is 

 generally placed in a coniferous tree, at a height varying from 

 ten or fifteen to fifty feet. The eggs, 3 or 4 in number, are creamy 

 white, spotted, specked, and rarely blotched with orange brown, 

 chiefly at the large end. Size — .64 x .52. 



These birds during the breeding season inhabit almost ex- 

 clusively the dense coniferous or mixed fofests, where in June 

 they build tlieir nests.
